Re: [talk-ph] DPWH 2012 Road Data
Well, there's a loophole in that provision. If what you get from the government is *pure data* (numerical coordinates, etc.), then you can't use it in OSM without permission. This is the idea behind the DepEd and DOH data we are getting/trying to get. On the other hand, if what you get is an image (e.g., map), then you are free to take facts that you can see when you look at the image/map. The Philippine IP Law follows the US IP Code in that facts aren't copyrightable. You can't use or distribute the map itself for commercial purposes without permission, or copy the creative aspects of the map (which are copyrightable) such as colors, styling, cartography, etc. without permission, for commercial purposes. But you can get facts that you have interpreted from the image and use that in any manner you choose because facts aren't copyrightable and the government did not give you that fact outright. Of course, we can just ask DPWH for permission.

Re: [talk-ph] ideas on importing deped schools db to OSM
Dear all, Just to update you on this. Upon random checking of some tiles, there are cases where the location is too far off. It was confirmed by Liana that in some cases, brgy boundary centroid was used when no actual gps survey was conducted. I will try to cleanup the data before we begin the import. Suggestions welcome.

I guess the dpwh's copyright restriction was just a copy&paste thing. I'm not sure I can give you a straightforward answer since I am confused myself sometimes. :) There is a concept of derived database and produced work in odbl. Depending on how you use osm data and distribute the output, it may fall on either of the above category. In fact, the default map tile is not odbl but cc-by-sa. The wiki has sample use cases. > I say let DPWH use it more on their projects silently, so that we'll have more proof..., and then it's easier to officially negotiate for sharing of government data in the future (give & take arrangements). :-) I think government use of osm is what most of us want.

Re: [talk-ph] DPWH 2012 Road Data
Clicking on Region IV-A on DPWH link: http://www.dpwh.gov.ph/infrastructure/Road%20Data/2012%20Road%20Data%20for%20Ipad/region_iv_a.htm Is it safe to classify Caylabne Road a trunk (an extension of Governor's Drive)? How about Naic-to-Mendez and the Tanza-Trece Martirez roads? Weird, Aguinaldo Highway & Sta-Rosa-Tagaytay Road classified as secondary, yet Calamba Road is arterial?? can't be Declassify as trunk (back to primary) the pagsanjan-louisiana-lucban route? (road is too narrow anyway) Calauan-Nagcarlan route is just a minor road on OSM but looks like a trunk going all the way to Tayabas on DPWH's map.

[talk-ph] Fwd: [OSM-dev] Website to generate polygons from OSM relations
Hi guys, See the following email for a new interesting service provided by a French OSM developer. Some example Philippine-related images generated using the service: Palawan : http://polygons.openstreetmap.fr/get_image.py?id=1506669¶ms=0 Metro Manila : http://polygons.openstreetmap.fr/get_image.py?id=147488¶ms=0 -- Forwarded message -- From: Jocelyn Jaubert Date: Wed, Jun 12, 2013 at 5:45 AM Subject: [OSM-dev] Website to generate polygons from OSM relations To: d...@openstreetmap.org Hi, I have put into production a website to generate various outputs from OSM relations, by taking into account inclusion of other relations. It is available at: http://polygons.openstreetmap.fr/ What it can do: - generate whole geometry from an OSM relation ID, with handling of sub-relations - this works especially well with the recursive French model for administrative relations, and can be used as a sanity check. - generate simplified geometries, even bigger or smaller - this is useful to cut a .osm file with a good .poly file. - export WKT, .poly, GeoJSON, or even a picture. - import a user .poly file, and then do an Union from an OSM relation. I used this to fix some polygons used for Geofabrik extracts. A few examples: OSM relation for Corsica: http://polygons.openstreetmap.fr/?id=76910 http://polygons.openstreetmap.fr/get_image.py?id=76910¶ms=0.02-0.005000-0.005000 Same thing for France (image is a little longer to generate) http://polygons.openstreetmap.fr/?id=1362232 Union of Geofabrik and OSM relation for PACA, a french region: http://polygons.openstreetmap.fr/get_image.py?id=8654¶ms=0.02-0.005000-0.005000&name=provence-alpes-cote-d-azur_5k3mbx (you can see that some part of the region were missing from the yellow polygon) The source code is available at: https://github.com/jocelynj/osm-polygons-generation This uses an osmosis database, containing the whole word, and some Postgis functions. If you have any suggestion, don't hesitate to propose them ! Thanks, Jocelyn ___ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph

Re: [talk-ph] GPS review on etrex 30 and 62sc
Hi Maning, I have a two week old etrex 20 and a Legend hcx. I know you were asking for the 30, but the only difference is the absence of the atmospheric barometer [1], magnetic compass, and the ability to connect to Ant+ devices. the 20 was a clear winner for me since it was cheaper and the extra features of the 30 wont be hugely missed for mapping. Here's a good review of the 20 [0] but the reviewers firmware was 2.2. I havent checked if the bugs have been resolved in 3.0, but i share most of his experience with the device the hcx reports a better accuracy against the 20 (gps+glonass) with a good view of the sky. however, the 20 is only slightly affected when there are tall buildings on one side of the road. on streets with tall buildings, the 20 shows slightly more drift than the hcx. having said all this, i feel the 20 reports a more conservative accuracy and is a bit more transparent with errors in logging tracks. A colleague has a 62 (not sure which model) and he just agreed to lend me his unit next week. :) if you'd want some comparisons between the hcx, 20, and 62, let me know your questions.
